LIQUID .PURIFIER.

Application filed. July 6, 1926. Serial No. 120,690.

This invention relates to filtering devices particularly adapted for usein the gasoline line of internal combustion engines, and my object is todevise a filtering device which is simple, effective, easily installedor disassembled and which -is to a considerable extent self cleaning. Iattain my object, by

means of a construction which may be briefly described as follows. Acircular base is provided With concentric seats to which are securedconical strainers, the outer being of wire while the inner is of chamoisor similarmaterial and is provided with a supporting device adapted tokeep it distended. To the base is detachably secured a casing providedwith a sediment chamber underneath the strainers, the outer strainersbeing pro-,

mediate its center and its circumference with g vided with an openingover the sediment chamber.

The invention is hereinafter more fully described and is illustrated inthe accompanyin drawings in which Fig. 1 is a longitudinal section of mypuri- Fig. 2 a cross section of the same; and Fig. 3 a detail, partly 1nsect1on,.shoW1ng the inner strainer. a

In the draw ngs like numerals of refer- Y ence indlcate correspondingparts in the different figures. I

1 1s a circular base plate provided intersupported in distended positionas it is not capable of self-support. For this purpose I provide meansengaging the apex of the cone and the base 1. In Fig. 1 I show a supportcomprising a coned disk 7 fitting in the apex of the strainer andcarried by a rod 8 formed on or secured to the base plate 1-.

In 3 I show a modification comprisa modification of the supporting meansfor ing a tapered coil spring 9 engaging the base within the flange 2and also engaging in the apex of the cone. To the base is secured thecasing 10 by means of the screws 11. This casing may be of anyconvenient form and isprovided beneath the strainers with the sedimentchamber 12 provided with a drainage opening normally closed by the screwplug 13. Above the sediment chamber an opening 14 is preferably formedin the outer strainer through which may pass any sediment fine enough topass through the outer strainer anri which has been caught by the innerstrainer.

In the outerend of the casing is formed an inlet 15 for connection witha gasoline supply pipe. A similar outlet 16 is formed in the base platebetween the flange 2 and the center of the plate'. A lug 17 is providedon the casing whereby the device may be secured to a suitable supportingpart.

It will be noted that the opening 14 in the outer strainer is locatedadjacent the base of the inner strainer. The liquid passing throughthedevice flows towards the bases of the strainers and thus cleans offanysediment on the inner strainer and carries it towards the opening 14.Thls arrangement of the opening also tends to prevent any fresh liquidfrom passing therethrough. lVhat I claim is:

1. A purifier comprising a base; an annular flange on the base. formedas a strainer seat an inner conical fibrous strainer having its openbase secured on said flange; a sup port for the inner conical strainerextending from the purifier base to the apex of the cone; an outerstrainer of wire also having its open base secured on' said flange; anda casing detachably secured to the base and provided with a sedimentchamber beneath the strainers, the outer strainer having a drain openingin its under side adjacent the base of the inner conical strainer andover the sediment chamber to permit of the escape of sediment frombetween the strainers.

2. A purifier comprising a base; an annular flange on the base formed asa strainer seat; an inner conical fibrous strainer having its open basesecured on said flange; a support for the inner conical strainercomprising a tapered coil spring engaging the puri- :fier base and theinner side of the inner coni- -nl fibrous strainer; am enter strainer ofWire also having its open hue eemred on said flange: and :1v casing(iemchzlbly secured f0 the base and mm Med wiih :1. sedimentehmnherbeneath the strainers the elder RtlflillCl' hnvme; :1 (1mm opening m Weunder side adjacent the base of the inner conical strame' and ever thesedlment chm'nber to permit of the escape of. sediment from be- 10 ROYD.
